Low Volume Production Solutions for Custom Metal Parts
Agile small-batch metal manufacturing — bridging the gap between prototype CAD design and full OEM mass production without expensive hard tooling or strict minimum order quantities.
Flexible Small-Batch Manufacturing Without High Tooling Costs
When launching a new hardware product or conducting field trials, traditional metal fabricators often turn buyers away with high Minimum Order Quantities (MOQs) or demand tens of thousands of dollars for hard stamping tooling.
Conwhole provides a specialized Low Volume Production solution engineered for high-mix, flexible batch orders ranging from 1 to 500+ units, utilizing tool-less laser cutting and CNC machining.
Key Takeaways
- No Hard MOQ Barrier: Order 1 to 500+ pieces without penalty fees or surcharges.
- Zero NRE Tooling Options: Fiber laser cutting and CNC machining eliminate hard dies.
- Fast Turnaround: Prototype-to-production pilot builds in 5 to 10 business days.
- Production-Grade Quality: Full CMM reports, documented QC, and material MTRs.

Why Choose Conwhole for Low Volume Production?
Zero MOQ & Fast Setup
We welcome small batch orders from 1 to 500+ pieces without penalty surcharges or strict minimum requirements, giving you complete flexibility for market testing and pilot builds.
Eliminate High Tooling Expenses
Our advanced tool-less fiber laser cutters and CNC machining centers allow us to manufacture complex metal components directly from 3D CAD files without investing in hard stamping dies.
Production-Grade Precision & CMM
Small batches receive the exact same rigorous documented quality enforcement as mass production, complete with full CMM dimensional inspection logs and material mill test certificates.
Smooth Pathway to Mass Scaling
When your product demand grows, we smoothly transition your low-volume production program to automated hard tooling, reducing unit costs while keeping identical quality specs.
Q1: What batch sizes qualify as “low volume production” at Conwhole?
At Conwhole, low volume production typically spans from 10 pieces up to 1,000 pieces per run. We also support single-piece prototyping (1–5 pcs) as well as recurring batch orders of 50–500 pcs.
Q2: Will I need to pay for tooling or dies for a 50-piece order?
In 95% of low volume projects, no hard tooling or expensive stamping dies are required. We utilize fiber laser sheet cutting, press brake bending, and CNC machining directly driven by CAD files.
Q3: How fast can Conwhole deliver a batch of 100 custom metal parts?
A standard batch of 100 sheet metal or CNC machined parts can typically be produced and surface-finished in 7 to 10 business days following 3D drawing approval.
Q4: Can I modify my 3D CAD design between small batch runs?
Yes. Because tool-less laser cutting and CNC machining rely on digital CAD programming, modifying part geometry between batches is straightforward and incurs no scrapped hard die fees.
Q5: Are the materials and surface treatments identical to mass production parts?
Yes. We use production-grade mill-certified metals (SS304/316L, Aluminum 6061/5052, Carbon Steel) and production-grade finishes (powder coating, anodizing, plating) so your test parts match mass production performance.
Q6: Do you provide CMM measurement reports for small batch orders?
Yes. We include full First Article Inspection (FAI) dimensional reports and CMM measurement records for key callouts on every small batch delivery upon request.
Q7: What happens when our product volume increases from 500 pcs to 20,000 pcs?
Our engineering team will design dedicated progressive stamping dies or automated robotic welding cells to drastically lower your piece-part cost while keeping identical dimensional specs.
Q8: How do I get an instant estimate for my low volume metal parts project?
Simply upload your 3D CAD files (.STEP/.IGES) and 2D PDF drawings via our online inquiry form. Our engineering estimating team will respond with a formal quote within 24 hours.
